I have a Multiplus II 48/5000/70 connected to a 14kHw 280Ah 52V LiFePo4-Battery with JK-BMS and Venus OS on RaspberryPi. A 6kWp photovoltaik system is connected AC-coupled on the AC-IN-side. Everything is working great except during sunny periods, the maximum battery charge current seems to be limited to 50A.
I checked all settings in VenusOS, all charge limits are set to 100A. VRM portal is also showing these limits:
DVCC charge limit is switched off, BMS CCL and DCL are also set to 100A.
I also checked with dbus-spy for any secred 50A limit but found nothing. Checked DC charge limit, but also showing 70A...
Downloaded Multiplus II configuration via VRM / Device list / Remote VE Configure and checked settings in VE Configure 3:
Settings seem to be correct here (Weak AC input = off, Charge curreng 70A)
Does anybody have any idea what else to check? Would be nice, if I could use the whole 70A charging current in specific situations (short sunny periods) to quickly charge the battery...
I already tried to search other questions about this topic but didn't find a good answer. The limit of 50A seems to be a fixed barrier.
Any help is appreciated.
